Grow in fertile, humus-rich, moist but well-drained soils in full sun or partial shade, with shelter from cold, drying winds. Creeping rootstock can become invasive in warm, moist or favourable conditions and need restraining ; see bamboo control and bamboo cultivation

Remove weak, dead, damaged or spindly stems in spring and thin to show off stems to best effect. Cut out any flowering shoots promptly to discourage more from forming - see bamboo cultivation

Propagate by division, separate rhizomes in spring, keeping divisions moist until well established

Slugs may damage new shoots

Generally disease free
